CARDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 236,408, dated January 11, 1881.

Application filed July 14, 1880. (No model.)

To all whom it may concern Be it known that I, GEORGE BERNHART, of Amana, in the county of Iowa and State of Iowa, have invented certain new and useful Improvements in Gaming-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

The object of this invention is to provide improved mechanism for taking end or waste rovings from the finisher-card and delivering them to the second breaker-card.

The several improvements will first be described in the specification, and definitely set forth in the claims.

In the drawings, Figure l is a longitudinal vertical section of the conveyerand co-operating parts. Fig. 2 is a side elevation of all the parts except the conveyer and the bonnet. Fig. 3is aplan view ofthe roll and shaft which drives the conveyer. Fig. 4 is a front elevation of the rolls which deliver the end rovings to the conveyer, said figure alsoshowing the rovings and the guide. Fig. 5 is a front elevation of one ofthe two pairs of supporting-rolls over which the conveyer passes, said pairs of rolls being duplicate in form. Fig.6 is a front elevation of acard-roll and its companion roll, said card-roll serving to take the rovings from the conveyor. Fig. 7 is a front elevation of the card-roll which delivers the rovin gs to the second breaker-card, said view also showing the means forreciprocating the cylinder-sh aft endwise. -Fig. 8 is a front elevation of the roll about which the conveyer passes atits end adjacent to the second breaker-card. Fig. 9 is a detail plan view of the guide which brings the two end rovings together and that portion of the bonnet which is located below the guide. Fig. 10 is a vertical transverse section of the bonnet.

The two end or waste rovings A pass the rub-rolls of the finisher-card A down to the guide B, the latter drawing the rovings to gether, so that they pass beneath the plainface horizontal roll 0 in position to be laid on the conveyer D. This guide is formed with two horizontal walls, a, adapted, respectively,

to provide lateral bearing for the two end rovings as the latter descend from the rub-rolls. The conveyer is an endless belt, provided on one face with card-clothing, and is driven by a groove faced roller, E, the latter being mounted upon a transverse rotary shaft, F, provided with pulley G, which is driven by a belt extending directly from the rub-rolls of the finisher-card. Roll 0 has a companion roll, H, formed with a groove face, in which the conveyor fits, said two rolls being journaled in a vertically-slotted standard, K, the extremities of roll U resting upon the end collars of roll H. The conveyer extends beneath and between the finisher-card and the second breaker-card. Its upper leaf passes over the upper roller of each of the two pairs of supporting-rollers L7 and then passes over the supporting groove-roller M, which serves as a companion to the card-roll N. The latter is a groove-roller having its groove provided with card-clothing, while its end collars are plain and bear upon the corresponding collars of roller M. This card-roll takes the rovings from the conveyer, and the rovings are taken from said card-roll by a plain-face roll, P, provided with card-clothing.

It will be understood that roll P is made substantially of the width indicated in the drawings to correspond with the requirements of its use. The end rovings are of small width, and do not require rolls which operate solely thereon to be of a width equal to that of the finisher-card and a second breaker-card. This statement also applies to the card-roll N and the width of card-clothing with which it is provided. The end rovings being comparatively narrow, the width of the card-clothing, respectively, on both said rolls N and P is appropriate to the work of the rolls.

This roll P is mounted upon a transverse rotary shaft, R, provided with pulley S, driven by a belt extendingfrom the shaft of the main cylinder of the second breaker-card, B. Shaft It is journaled in standards T, in which it has free endwise movement. One extremity of the shaft is provided with an annular cam, a, which works in a groove, 1), formed in bracket 0, secured to the corresponding standard. As the shaft is rotated this cam-and-groove device imparts a longitudinal reciprocation to the shaft, thereby delivering the rovings to the main cylinder of the second breaker-card, and distributing the fibers evenly thereon.

The two card-rolls are located above the conveyer at different points in its length, the second card-roll, B, being larger than the first card-roll, N, and located rearward thereof. The first card-roll is intended to take all the wool from the conveyer and deliver it to the second card-roll; but the latter is maintained in such vertical position relative to the conveyer that it may strip the same perfectly clean in case the first card-roll does not do it. The appropriate end of the conveyer passes about roll V, and the lower leaf passes over the lower roller of each of the two pairs of supporting-rollers L. In passing from roll V to the adjacent roll,over which the lower leaf passes, the latter is given a half-twist, so that the card-clothing may be free from contact with both said lower rolls. The lower leaf is given a return half-twist in passing to roll E from the adjacent lower roll of the pairs of rolls L, so as to bring the card-clothing into position for passing over roll E. An adjusting device, a, maintains roll V at different distances relative to roll E, thereby adapting the conveyer to have a greater or less degree of tension imposed thereon for runnm l folls M and N are journaled in a frame, 0, mounted upon a horizontal bolt, D, which latter is supported in the upright arms a of a stand, E. The bolt is provided with a nut, F, by which the arms a may be clamped against the frame 0 and hold the latter in position.

By adjusting the frame 0 the card-roll N may be maintained at different distances relative to card-roll P. This adjustment, it will be observed, is attained by securing the frame 0 at different degrees of vertical inclination.

The bonnet W fits over the conveyer and its co-operating parts, and preserves them from the dirt and waste matter which drop below the cards. The bonnet is made of transverse sections, and any section may be removed for cleaning and lubricating the conveyer. The bonnet fits over longitudinal strips, 20, secured to the floor, and is thereby held in position.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a finisher-card, a second breaker-card, and a conveyer extending between the two cards, of a roller about which the waste rovings pass as they are laid on the conveyer, and a guide located above the roller and adapted to bring the two end rovings near together in their passage to said roller, substantially as set forth.
